DARI'US WILCOX, OF CHARITON, IOWA.

Letters Patent No. 94,052, dated August 24, 1869.

To all whom it may concern Be it known that I, DAlnUs WILoox, of Ghanton, in the countyof Lucas, and State of Iowa, -have in' vented a new and-useful Improvementin Fanning- Mill and Grain-Separator; and Ido hereby declare that the followingv is a full and exact description of the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

This invention relates to an improved tanning-mill,- and consists, mainly, in the combination' and arrange' ment of the various parts, by means of which animproved result is obtained. The details of construction and manner of operation will be fully described hereinafter. 4

In the drawings- Figure 1 represents a side elevation, and

Figure 2, a central vertical section of my improved mill.

To enable others skilled in the art to makeand use my invention, I will now proceed to describe fully its construction and operation.

a represents a hopper, into which the grain is placed.

This is provided with a slide,'J, by' means ofwhich the opening i's varied, and the delivery of the grain regulated.

b represents the rst set of riddles. structed in any suitable manner, and arranged in any suitable way.

No. 1 represents the first fan. This is so arranged that its blast is forced into the chamber o', and is thus compelled to pass through the riddles b before it can pass from the machine. By this arrangement every portion of the grain is reached.

After passing through the riddles b, the grain falls upon the board k, which, being inclined, conducts it to the second set of riddles, c. Here the grainis again acted upon in a similar manner, by means of fan No. 2.

These are con- 'Passing through these riddles, the grain failing upon the inclined board d, is delivered at'themouth of the l pelled, as itwere, to pass three sides of a square while exposedto the blast.

The fans and riddles may be operated by any snitaule system of pulleys and gearing. I preferably' operate the riddles by means of an eccentric, m, which 'gives these kthe proper reciprocating motion',

The springs n extend entirely across tbe openingin the mill, and are. secured to the Vriddle-case at about the centre, being suitably bent inward for that purpose.

By the arrangement described, a compact and eficient fanning-mill is obtained. ,4

Having thus fully described my ,inventiom What I claim as new, and desire to secure by Let# ters Patent, is

1.The fans, Nos. 1, 2, and 3, when arranged substantially as described, for the purpose set forth. 2. The mill described, consisting essentially of the hopper a, riddles l) c, grain-boards k d, and fans 1, 2,4

3, when combined and' arranged as and for the purpose described'.-

This specication signed and witnessed, this 21st day of.Ji1ne, 1869.
